Signal decoding is the process of interpreting and converting signals into a format that can be understood. This is commonly used in telecommunications, where data is transmitted over various mediums, such as radio waves or fiber optics. The goal is to retrieve the original information from the received signal, which may have been altered by noise or interference during transmission. In digital communication, signal decoding involves algorithms that analyze the received signals and reconstruct the original data. Techniques like error correction and modulation are often employed to enhance the accuracy of the decoding process. Successful signal decoding ensures reliable communication in various applications, from cell phones to satellite systems.
